How do you set the timing on a Datsun b210?

To set the timing on a Datsun B210, first ensure the engine is at operating temperature and then turn off the engine. Locate the timing marks on the crankshaft pulley and the timing cover, then use a timing light to check the current timing. Adjust the distributor by loosening its hold-down bolt and rotating it until the timing light indicates the desired timing mark aligns with the pointer. Once set, tighten the bolt and recheck the timing to ensure it is stable.
